Builder

Create and manage your custom projects from scratch with CrowdFlower’s powerful platform.

Should I use Builder?

If you are a self-starter who wants to build a crowdsourcing job with minimal support, get started with Builder. The best types of jobs are data-centric projects that can be split into many simple, repetitive tasks.

If you are seeking a custom built solution with additional customer support, then building it yourself may be difficult. For highly complex projects that require specialized skill sets, try a custom solution.
